Hello Rachel,
Im not an expert in beagles BUT I have been told that they are not the type of dog for a first time owner as they are quite hard to train and can also be rather stubborn.
However I dont know if you have had one and I hope to think that you have read the books, visited the shows, talked to breeders etc so hears the website you need to help you find a breeder in your area :)
http://www.the-kennel-club.org.uk/ and click on ''searching for a puppy?'' (you'll have to sign up but you get a map of england with the lists of KC breeders.)
Good luck :)
